After the B-ultrasound is turned on, please check the following items:
There must be no abnormal sounds, strange smells or overheating.
2. Check whether the device starts normally: the power indicator light is on, the screen displays the startup screen, and then it automatically enters the B mode.
3. Check whether the acoustic lens is abnormally heated when the probe is in use. You can feel the temperature of the probe by touching it with your hand.
4. Check the image to ensure that there are no abnormal phenomena (such as abnormal noise, flicker).
5. Check the control panel to confirm that it is working properly.
6. Check the fuselage to ensure that there is no excessive temperature rise locally.
